short focus Rodagons for micro format or macro work

I have two 'new' (minus packaging) Rodagons that I bought a few years back as part of a complete set of focal lengths that I simply don't find myself using. They are:

28mm/4 Rodagon - $85
35mm/4 Rodagon - $85

They would be fantastic either for someone doing half frame/minox stuff or someone wanting to get into serious macro/micro work with any format.
